HAYS TAGKER Filed April 17. 1929 3 Sheets-Sheet 3 v Attorney Patented Jan. 6, 1931 raenx GRABOWSKA, or more, son'rn' DAKOTA HAYSTACKER Applieation filed April 17, 1929. SeIiaIQNO. 355,801.

The present invention appertains to new and useful improvements in hay stackers-i;

and more particularly to a hay stacker of the fork type. The main disadvantage found 5 in the use of stackers now generally employed is that the hay piled upon the fork tends to loosen and fall off as the-fork is the ground, so the present invention has as its principal object the provision of a novel 1O forkwhich will fore the load is actually lifted from the move into a stack of hay beground. v

After considering the following specification and claim, other very important b ects H and advantages of the invention will become apparent.

In the drawings v Figure 1 represents a top plan view of the. improved hay stacker. Fig. 2 represents a side elevation of the improved stacker.

Fig. 3 represents a fragmentary horizontal sectional view disclosing the fork retaining means. Fig. 4: represents a fragmentary vertical sectional view disclosing one of the slidable fork shanks.

'Fig. 5 represents a fragmentary vertical transverse sectional view taken substantially on line 5-5 of Figure t.

Fig. 6 represents a perspective view of the notched arm which retains the fork inits normal position.

Referring to the drawings wherein like like parts, it will be seen 85 numerals designate that the invention includes a rectangular frame consisting of side bars 5 connected at their ends by the cross bars 4, each side bar 5 having. an elongated beam 6 pivotally connected thereto by its end as at 7 and a cross bar 8 interconnects the pivotal'endportions of'the beams 6. H Y

Thebeamsfi extend forwardly of the. afore-v mentioned frame, andproi ect beyond the forward end thereof. The beam 6 has a pair of spaced guide straps 99, at its free end portion through whichthe shank 10 of the fork structure 11 is slidably supported. 1 The shanks 10 are interconnected by a cross bar 12, at their intermediacy.

lifted from by bolts 16 throughthe forward end portions The free ends ofthe beams 6 are-formed with openings throughwhich the ends of a shaft 13, are rotatably disposed. Theishaj'ft ends also protrude thru slots 1a inthe for- 'ward end portions of the "shanksj10,.- asis;

clearly shown in Fig. 3. n I

. Arms 15 arepi'votally connected at one end of the shanks 10 and these arms are-provided with slots 17 registrable with the slots 1a .of

.the shank 10. A. spring 18 serves to normally swing the free end; of the arm downwardly and-as clearly shown'in Fig. 3, the slot 17 V -Iserves to receive one end of the shaft 13.

A suitablestop member 19 limits the-in ward movement of the shaft. The fork structure is of generally conventional construction, including aback bar 20 and a plurality of tines 21 projecting forwardly therefrom.

Thetinesare bridgedby across piece 22 and from the rearward endof the backward end portion of each tine, an upright .member23 is secured. p r

Adjacent each beam 6 acollar2etis attached tothe shaft 113 and from each colla'r projects a bell crank 25 and a short arm 26. A rod 27 extends from each bell crank 25 to an eye 28 on the apex portion of the V-shaped pivotal hoist frame 29. An eye member 30 is provided at the apex for submitting the attachment thereto of a cable 31 which is disposed rearwardly and trained beneath the pulley 32 mounted upon the cross member 4 of the aforementioned rectangular frame. A link member 33 connects between each short; arm 26 and an eye member 34 on the cross beam 12 connecting the shanks 10.

' Asis clearly shown in Fig. 6, the forward end of the slot 17 inthe pivotal arm 15 is provided with an upwardly disposed notch 35;:

It will thus be seen that when apull is inwill' pull' on the rod 27 and rotate the shaft 13. 1

The shaft 13 rotating will exert a pull on the link 33 which will pull the shank 1O for- Wa'rdly thus driving the tines of the fork 11 into a hay stack. 1

hen the load is well on its upward StI'0k8,' the fork will slip backward to its original position. 'When the original position reached, the arms 15 will gravitate so that the notches will receive the ends of'the shaft 13, thus retaining the parts against slipping when the fork again reaches the ground where the'arm will engage the ground to release the shaft 13 from the notches 3 5. I

The lower portions of the arms 15 arefnormally disposed so that when the fork'is'lowered, the arms will engage the ground from 7 the sprints 18, so that the shaftv 13 becomes disengaged from the notches 35L" It is to be understood that various changes 7 i in the specific shape, size, materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

I claim as new is :7-

A hav stacker of the character described,

comprising a slidable' fork having longitudinal and transverse brace elements, a pivotal carrier for the fork, bracing means for lifting the carrier, a supportingframe to which said carrier and bracing means are pivoted,

means for shifting the taneously means, said means comprising a transverse fork forwardly simulshaft being secured to the carrier frame, levers rigidly secured tofthe ends of said i shaft, link members conneoted with the levers i I and saidslidable fork rake, means for securing the fork in itsnorma'l position, said means 1 "consisting of an arm member pivotally connected to the frame, saidarm having a notched slot, said transverse shaft disposed in the slotted portion of' the arm, and

adapted to seat in'the notched recess upon elevation of the fork.

. A In testimony whereof I afiix no signature.
